Video Body Swap

Video Body Swap

Video Body Swap replaces the body in a target video with your face. Upload a face image and a body video — AI seamlessly composites your likeness onto the moving subject, frame by frame, with natural blending and consistent identity throughout the clip.

Why Choose This?

• Seamless face-to-body compositing Advanced AI tracks the subject across every frame and blends your face naturally onto the body in motion, maintaining consistent identity and lighting.

• Simple two-input workflow Just a face image and a body video — no masking, no manual keyframing, no technical setup required.

• Wide range of use cases Works across talking head videos, dancing clips, fitness content, and more.

• Production-ready API No cold starts, predictable per-second pricing, and a ready-to-use REST endpoint for seamless integration.

Parameters

How to Use

Pro Tips

• Use a high-quality, well-lit face photo with a clear, unobstructed view for the most natural compositing result.
• Videos with a single clearly visible subject and stable lighting produce the cleanest swaps.
• Avoid heavily cropped or low-resolution face images — the more facial detail the AI has, the better the blend.
• For best results, the face in the image should be roughly front-facing and similar in angle to the subject in the video.
